Analogy type questions:
$(1)$ Sponges,Coelenterates : Respiration through entire body surface :: Insects : ....
$(2)$ Larynx : Cartilaginous box :: Epiglottis : .......

(A) $(1)$ In sponges and coelenterates,respiration occurs via simple diffusion across the entire body surface. Similarly,insects respire through a network of tubes called tracheal tubes (tracheae).
$(2)$ The larynx is known as the cartilaginous box (sound box). The epiglottis is a thin,cartilaginous flap that prevents the entry of food into the glottis during swallowing.
